Former United Kingdom Prime Minister Boris Johnson alleged in an interview with The Telegraph that his staff found a "listening device" in his personal bathroom after Israeli Prime Minister Benjamin Netanyahu had used it in 2017. Johnson had been a foreign secretary at the time. Johnson claimed ahead of the release of his book "Unleashed" that he was told "later, when they (security) were doing a regular sweep for bugs, they found a listening device in the thunderbox.” When asked for more detail during the interview, Johnson said "everything you need to know about that episode is in the book.” The Telegraph reported that "it is not clear whether Israel was questioned or rebuked over the incident." Israel also was accused around the same time of planting listening devices in The White House, The Telegraph also reported. U.S. officials said that "Washington concluded that Israel was likely behind the placement of cellphone surveillance devices that were found near the White House and other sensitive locations around the capital," The Telegraph wrote. The Hill has contacted the Israeli Embassy in London for comment.
